11. A. B. C. D. E. 12. A. B. C. D. E. 13. A. B. C. D. E. 14. Identify the correct pairing of term and definition. Enthalpy-temperature Endothermic reaction in which energy is released Specific heat-amount of energy required to raise 1 g of a substance 1 degree Celsius (or 1 Kelvin) Joule the unit that measures temperature None of the above At a constant pressure, the following reaction is exothermic: 2NO₂ (g) → N₂O4 (g). Which of the following statements is true about the reaction (as written)? The reaction is always spontaneous. The reaction is spontaneous at low temperatures but not at high temperatures. The reaction is spontaneous at high temperatures but not at low temperatures. The reaction is never spontaneous. None of the above When 45 g of a metal alloy at 25°C, is dropped into 100.0 g of water, the alloy absorbs 956 J of heat. If the final temperature of the alloy is 37°C, what is its specific heat? 0.423 J/g C 0.797 J/g C 9.88 J/g C 48.8 J/g C None of the above If the reaction represented by the diagram above were conducted respectively at temperatures T₁ and T₂ (where T2 > T1), then the Boltzmann distribution for the reaction conducted at temperature T₂ would reflect: A. a larger area under the curve for T₂ than for T₁ B. a curve with the same area, but lower peak height than for T₁ C. smaller area under the curve for T₂ than for T₁ D. an activation energy at T₂ which was higher than that at T₁ E. a curve with the same area, but higher peak height than for T₁
